Lilygo T5-4.7 inch ESP32-S3 (aka "plus"/V2.3) e-paper board

I have the "T5 4.7 Inch E-paper V2.3" (aka "LILYGO T5-4.7 Plus") board.

The vendor published the board json here: https://github.com/Xinyuan-LilyGO/LilyGo-EPD47/blob/f6a4fabbfba39f29fcc166d1b8a87c342a379b99/platformio/boards/lilygo-t5-47-plus.json

What's the procedure for adding it to the tree? (I see that sometimes the JSON simply gets committed, in other cases an arduino board config is requested first.)

Once Xinyuan-LilyGO/LilyGo-EPD47#107 is resolved (either by removing ARDUINO_RUNNING_CORE from the json, or on the esphome side), this would simplify the process of using it with esphome a lot.

Hi @nickolay, usually a variant header file with proper pin definitions in the Arduino core is required just to avoid frustrating issues when default pins (e.g. LED_BUILTIN) doesn't correspond to the real hardware.
